We are building a DR site and are having trouble mapping drives from our local machines to the server at the DR site. The new server will be a SQL Server 2005 server. We have resolved many of our issues of connectivity and can RDP to this box however everything seems to be slow.
The domain at the DR site is different than our domain. So when connecting I preface the user account with the domain account. I have shared a folder on this box and am trying to map a drive on my desktop. I am having inconsistent results. Sometimes it seems to work. Sometimes it works then fails and then sometimes it refuses to work. I am mapping the drive using a cmd window and the net use command and also opening up a windows explorer window and using the map drive command from the GUI.
I suspect all of this is happening based on some kind of authentication problem as it tries to validate mycredentials for each action I try. As I understand it drive mapping takes place through the use of port 445 which is open. We are having trouble getting high ports open due to policy issues. I don't know if I need any other ports open to do this ( I am a database admin, not a server guy) but, to me, if it was failing due to a random high port issue it might look like this also.
